  (30, 72, 78)

Step-by-step explanation:

When testing a number of triples to see if they are Pythagorean triples, it can be convenient to let a spreadsheet do the math. The attachment shows us the triple at lower left (30, 72, 78) is a Pythagorean triple. That is, the sum of the squares of the smaller two numbers is the square of the larger, so they can form a right triangle.

You may recognize these numbers have the ratios 5:12:13, the ratios of an often-used triple.

Smooth Paint

Step-by-step explanation:

Glide Paint is the simplest and cheapest: 28.92 per gallon

Smooth Paint is 3 quarts for 22.75. That equates to roughly $7.58333333 per quart. There are 4 quarts in a gallon. So $7.583333333*4 = $30.33 per gallon

One-Coat Paint is 4 pints for $15.00. There are 8 pints in a gallon, so double $15 and you get $30

TL;DR: Glide Paint: $28.92, One-Coat Paint: $30, Smooth Paint: $30.33
